Single Plate Check Valve VS Dual Plate Check Valve

Single plate check valve and dual plate check valve are two foremost types of check valves that are typically compared each alongside, but what are the differences and similarities among the two, and how will you find that which one is best for you?

Both of these helps in preventing the backflow of fluid in the pumping system and are used in the oil and gas industry application. As such, they guarantee that the mechanical material within these valves is safe. But, what these check valves do for water? Let’s find it out!

What are the check valves?

A Dual check valve is a mechanical valve that opens when fluid passes forward but closes when liquid backflows. The valves do not rely on an individual; they operate automatically, depending on the reverse and forward flow of water. Similarly, check valves produce a slamming effect as they prevent reverse fluid flow.

What are the dual plate check valves?

Dual plate check valves are used in some regions as they have an ill slamming effect.

What are single plate check valves?

A single plate check valve, on the other hand, is an economical type of check valve. Their disk or closure is installed on the bottom, and it ordinarily moves around the hook. Also, the end is opened as an outcome of water forcing it to move. The force of water f and restrict the backflow of the water by closing the end. This will gives off the slamming effect.


While a single plate check valve is highly economical, their slamming effect makes them an unpopular choice as compare with double plate check valves. The end comes with the advantages of decreasing total cost while also enabling fluid flow in the pumping system without harming its mechanical appliances.

Dependent on this information, you too can make a pick, which can provide you with the least noise while you’ll also save on charges that would come tied with the check valve’s installation, energy consumption, and maintenance.
